摘要： A limiting orifice through-air-drying apparatus for papermaking or other absorbent embryonic webs. The apparatus has a first zone and a second zone. The first zone is maintained at a differential pressure less than the breakthrough pressure, while the second zone is maintained at a differential pressure greater than the breakthrough pressure. The residence time of the embryonic web to be dried with the apparatus is maintained at preferably less than 35 milliseconds on the first zone. Using the dual zone system described above, the overall energy required to run the apparatus can be reduced.

摘要： A papermaking belt, comprising either a forming wire or a through-air-drying belt. The papermaking belt comprises a reinforcing structure having two layers tied together and a resinous framework. The yarns of the first layer are interwoven so that, except for the tie yarns, each yarn remains within 1.5 yarn diameters of the top plane defined by the knuckles of the first layer. The belt has a thickness of at least 2.5 times the yarn diameter for rigidity.
